ABSTRACT:
A fixed codebook search method includes initializing a counter, searching for pulses and calculating the value of a cost function Qk, initializing the counter if the Qk value increases, increasing the value of the counter if the Qk value does not increase, judging whether the value of the counter is greater than the threshold value, continuing the search process if the value of the counter is not greater than the threshold value, and ending the whole search process if the value of the counter is greater than the threshold value.
